8 8 Summative Test and Attitude & Attribute Evaluation B efore the knowledge test is undertaken, the learner must be reminded of what is expected from him / her in terms of summative and reflexive competence. Read and explain to the learner, the Preparation for Your Final Assessment section in the learner workbook. Learners and assessor should sign off this section to acknowledge that this step was completed. Please set up a knowledge test from the questions given as a guideline to learners and supply each learner with a test sheet. Supply each report with the following heading: Unit Standard: NQF Level: 3 Learner Name: Questions Model Answers 1. Explain why pest weeds and diseases should be monitored. 2. Describe and discuss the most commonly used monitoring techniques used in your industry. In order to prevent crop damage occurring from insects, weeds and diseases it is essential that crops be inspected regularly. Crop monitoring indicates the pest status and extent of the crop diseased and the number of weeds that may be present. In this way the crop producer remains informed of the health status of his crop. Information on the crop disease and pest status enables the farmer to make decisions on whether control actions need to be taken, and select a suitable control action. In this way the farmer can e.g. chemically treat crops as and when required instead of according to a strict spraying programme, so reducing the costs of pest management.

9 9 3. Explain the difference between predator and pests. 4. Identify the major weeds relevant to your crop industry 5. Identify the major insect pests relevant to your crop industry 6. Identify the major forms of disease damage to your crop industry 7. Why is it important to keep a record of the pest monitoring data. 8. Name the major forms of monitoring tools for insect pest used in your crop and describe how they are implemented. 9. Name the major diseases of relevance to your crop, and discuss how they are identified. 10. Name the 5 most important weeds in your area 11. Discuss the monitoring system used in your industry for the identification of weed problems. Start with the process of weed identification. Predator refers to an insect that will feed on other insects; they therefore do not threaten the crop, but rather aid in the control of pests. Insect pests are insect that feed on the crops plant thereby causing damage to the crops. It provides data on the extent of infection and therefore the potential impact of the particular pest. It also provide a way of determining whether the pest is increasing over time.

10 Explain the three levels of weed management Prevention - prevention are the measures taken to prevent a new weed from entering an area. Preventive measures must also be taken to prevent weed seed from forming. Prevention includes avoiding: Crop seed contaminated with weed seed Spreading plant parts with implements Using contaminated manure Using contaminated irrigation water. The formation of seed on the weed plant spreading of vegetative reproductive plant parts Control - Weed control is the general objective in weed management. Chemical and mechanical weed control is the most predominant weed control techniques used. Weed control performed to reduce the numbers of weeds such levels that they do not adversely affect crop yield or interfere with the harvesting process. A balance must be struck between weed control costs and economic advantages in the form of larger profits. Eradication weed eradication is the elimination of weed plants and their reproductive capacity from an area. The only manner in which eradication can be performed in soil, is fumigation with soil sterilants. Such application of fumigants is expensive and profitable only when used on small areas of high-production soils or systems with the production of high value horticultural and vegetable speciality crops.
